The load balancer service-add command fails with error below while attempting to add service to the existing service group using port 15672.

Here is my command syntax:
slcli loadbal service-add local:79187 --port=15672 --weight=1 --healthcheck-type=4 --ip=174.37.219.102

I have also tried with ip address argument name spelled out as "--ip-address" resulting same error. Is my syntax incorrect or is this a bug?

An unexpected error has occured:
